Product overview The Whadda electronic scale load cell sensor package combines both an accurate load cell rated up to 20 kg, and a sensitive A/D converter board that easily interfaces with a large variety of microcontrollers (such as an Arduino® compatible board). In order to get accurate readings, the fixed side of the load cell should be mounted to a fixed, secure part. It is recommended to also mount a sturdy measuring surface where the weights can be placed upon to the measuring side of the load cell.

Example program You can download the example Arduino® program by going to the official Whadda github page: github.com/WhaddaMakers/Electronic-scale-load-cell-sensor 1. Click the “Download ZIP” link in the “Code” menu: 2. Unzip the downloaded file, and browse to the calibrate_sensor folder. Open the calibrate_sensor Arduino® sketch (calibrate_sensor.ino) located in the folder. 3.
. Once the correct weight is showing, type in the d character (1) and press send (2) to indicate that the calibration process has finished. Select and copy the resulting #define statements containing the calibration parameters (3). 8. Open the read_weight.ino sketch, and paste the copied #define statements in lines 32 and 33: 9. Upload the read_weight.ino sketch, and open the serial monitor by clicking the serial monitor button , make sure the baudrate is set at 9600 baud.
